KEMET Webinar

Aluminium electrolytic capacitors have been around for many decades. They are suitable solutions when high ripple current and high capacitance is needed. ESR and life have long been the drawbacks of aluminium electrolytic technologies. Polymer seeks to change that.

In this webinar, Austin Finley, Associate Technical Product Manager at KEMET, introduces the...

Today’s automobiles provide a prime example. In a single vehicle, you can find Wi-Fi, Bluetooth, satellite radio, GPS systems, LED lights, air conditioning, power steering, anti-lock brakes, rear-view cameras, and other instrumentation. Numerous items also operate using dc motors, including power seats, adjustable mirrors, windshield wipers, power windows, and sunroofs. This same example could also apply to items ranging from Wi-Fi or Bluetooth-enabled appliances like washing machines, espresso machines, medical instruments, and even medical implants.

Tantalum nitride-based precision thin-film resistors are impervious to corrosion caused by moisture because they are self-passivating. The RTAN series from Stackpole is a tantalum nitride thin film chip resistor that withstands biased humidity testing at 85oC, 85% relative humidity, ten per cent rated power with very little resistance shift
